Overview

The GPS sample application implements a travel calculator
that tracks the current location (using longitude,
latitude, and altitude), direction, grade, and travel speed.

The GPS sample application uses the LocationProvider
API
to collect the GPS
location information from the BlackBerry® device.

The sample application displays the information nearly simultaneously and updates the information at intervals that constants in the
application specify.

The sample application also stores waypoints in
persistent storage. These waypoints are recorded at intervals
that constants in the application specify. The waypoints record the
date and time they were taken, the distance travelled (using longitude, latitude, and altitude), and the average speed since the last
waypoint.
